Abstract
A self-consistent calculation of the potential-energy surface for a molecule () on a metal surface [Mg(0001)] is presented. The following experimentally observable adsorption features are identified and interpreted: (i) an activation barrier for molecular adsorption, (ii) a mobile molecularly chemisorbed state ("precursor state"), (iii) an activation barrier for dissociation (), and (iv) a strong dependence of on the adsorption-site geometry.
